I do think that the way certain people live can be improved, look at the carbon use of rich people in the USA compared to the average person in other countries. Larger houses, cars, more of everything, it all adds up.

Its fine to think that - and you're probably right. But again the solution will never be to ask people to change their consumption habits and their way of life. Its a non starter. The smarter thing to do is tweak incentives. A simple tax on electricity for example: now its more expensive to heat or cool a large house, leads to smaller homes, leads to more energy efficient units. That has a way way more impactful result than telling individuals what to do and how to do it.

There is no "the way to solve climate change" anyway. It's a challenge so huge that it will require us to change something about everything we do and the way we do it.
